LA @LI/tige?? tend above the top of the body 10, as illustrated in Figs. 1, 3 and 4.

' A standard 24 is Acarried upon the body 10 at a point in the rear of the pocket 13 and the beveled gear 25 is rotatably supported upon the standard 24. It will be noted that the beveled gear 25 is provided with teeth 26 upon its periphery, as shown in Fig. 4. When the device is in use, the teeth 26 engage the rack 23, formed on the blade 5, for purposes to be hereinafter set forth.

A housing 27 is fixed in any desired manner upon the body 1 0 and this housing is provided with a journal 28. The shaft 29 is carried by the journal 28 and extends into the housing and carries a beveled gear 30 upon its inner end, which meshes with the beveled gear 25. A grip 31 is carried upon the outer end of the shaft 29.

Therefore, it is obvious the grip 31 may be grasped and rotated, thus imparting rotary vmotion to the shaft 29. This action causes the gears to be rotated and as the gear 25 rotates, it is obvious it will shift the blade 20 vertically, in view of the engagement between the teeth 26 of the gear 25 and the rack 23 of the blade 20. Thus, the blade may be adjusted with respect to the degree with which it is to extend beyond the lower portion of the plane body 10, for different kinds of work. j

The clamping block 32 is elongated and extends into the pocket 13 formed in the plane body 10. This block 32 is provided with an off-set lug 33 which bears upon the blade 2O in alinement with the housing 27, while the lower end of the block also bears upon the blade in alinement with the slantling wall 14 of the pocket 13. This block is provided with a longitudinally extending slotv 34 formed therein, as shown in Fig. 4 and it will be noted that the slot 34 is in direct alinement with the slot 22 formed in the blade 20.

The clamping bar is indicated in general at 35 and it will vbe noted by referring to Fig.l 4 that this clamping bar extends longitudinally of the plane body 10. This clamping bar 35 comprises a thickened body 36 having a reduced shank 37 extending from one end thereof, while the neck 38 extends beyond the shank 37. The body 36 is carried within the pocket 13 in the plane body, although it will be seen that the shank 37 extends through the slot 34 vformed in the v clamping block 32, thus allowing theY rear end of the body 36 to bear upon this clamping block.A The neck 38 extends through the slot 22 formed in the blade 20 and thus allows the shank 37 to bear upon the blade 20. The rack 39 is formed or carried on the forward end of the body 36 and this rack 39 extends through the bore 19 formed in the plane body 10 and also projects into the 5,5 Soeren is. it will be noted ,that the rack sa.

is guided in its movement by a bearing plato 40 carried by the plane body adjacent the bore 19.

The shaft 41 is rotatably mounted upon theV plane body 10, extending transversely thereof, to have one end projecting into the pocket 18, while the opposite end will extend beyond the outer surface of the body 10, as illustrated in Fig. 2. The outer end of the shaft 41 is provided with a milled grip 42, while a pinion 43 is keyed upon the inner end o'f this shaft. This pinion is in position to mesh with the rack 29, as shown in Figs. 2 and 4. Therefore, when the grip 42 is grasped and the shaft 41 is rotated, rotary motion will be imparted to the pinion 43 and then to the rack 39. Therefore, the clamping bar may be moved in either of two directions for clamping the blade 20 in a set position or for relieving the clamping action for permitting of adjustment of the blade. It will be seen that the outer portions of the socket may be covered by a closure plate 44 retained in position by screws or other retaining means 45.

When this device is in operation, the grip 42 may be actuated for rotating the shaft 41 in a counter-clock-wise direction, thus causing the pinion 43 to move the rack 39, thus moving the clamping bar 35 forwardly. Therefore, the clamping block 32 and the blade 20 will be released from their clamped adjusted position. The grip 31 may then be grasped and the shaft 29 rotated in either of two directions, thus causing the beveled gears 30 and 25 to be rotated, whereupon the teeth 26 will cause the rack 23 to shift the blade 20, either upwardly or downwardly. Therefore, the cutting edge of the blade 21 may be moved to a desired position with respect to the bottom of the plane body 10, for allowing various thicknesses of cuts to be made when the plane is in use, for either making comparatively thick cuts upon the timber or for finishing work, owing to the manner in which the blade is adjusted. After the blade has been moved to an adjusted position, the shaft 41 may be rotated in a clock-wise direction, thus causing the pinion 43 to shift the clamping bar rearwardly and bring the same into a binding engagement with the clamping block 32 and with the blade, for clamping the blade in an adjusted engagement with the rear wall of the body and also with the housing, thus causing the blade to be held against accidental movement when the same is in operation.

After the blade 2O has been adjusted and is finally clamped by the block 32 in position, this block in turn beingretained by the clamping bar 35, the operator while gripping the plane body will also hold the grip 31 between the thumb and linger of the right hand while his hand will hold the plane body, while the left hand of the operator may fit over the forward portion of the plane body and the grip 3Q, may likewise be held by a thumb and finger, thus causing the clamping means to be firmly held in position to hold the blade 20 in an adjusted posi' tion.

The foregoing description and the drawings have reference to what may be considered the preferred, or approved, form of my invention. It is to be understood that 'I may make such changes in construction and arrangement and combination of parts, materials, dimensions, et cetera, as may prove expedient and fall within the scope of the appended claims.

Having thus fully vdescribed my invention, what I claim as new and desire to secure by Letters Patent, is

l. In a device of the class described, the combination of a plane body, a vertically adjustable blade carried by said plane body, a clamping block bbaring upon said blade, a clamping bar shiftable longitudinally of said plane body and engaging said block and blade, and a rotatable pinion carried by said plane body and engaging said clamping bar,

for adjusting and holding the same in a set position, whereby said bar will hold said block and blade in a set position as and for the purposes set forth.

2. In a device of the character described, the combination of a plane body, a vertically adjustable blade carried by said plane body, a clamping block bearing upon said blade, said block and 'blade having alined longitudinally extending slots, a clamping bar movable longitudinally of said plane body, said bar comprising a thickened body having a reduced shank terminating in a neck, said shank extending into the slot of said block and said neck to the slot of said blade, thus causing the bar to bear upon said block and blade, the forward portion of said block having a rack, and a rotatable pinion carried by said body, and meshing with the rack to shift the bar for holding the block and blade in a set position.

In testimony whereof I affix my signature in presence of two witnesses.
